Loading device

Abstract

A device that may be mounted on a bed of a pickup truck to enable smaller vehicles, such as motorcycles, snowmobiles, or all-terrain vehicles to enter from the ground level upon a platform of the loading device. This is accomplished by the loading device having a ramp that can be pulled outwardly or rearwardly from said device, and a motorcycle can drive up the ramp to the platform. A dolly slide is pulled outwardly from the device, and extends above the tailgate. The ramp then extends downwardly from the dolly slide, so that no weight or load is displaced on the tailgate.
